SY58018UMG-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58018UMG-TR is a high-speed, ultra-precision differential LVPECL 2:1 multiplexer manufactured by Microchip Technology. It supports data throughput up to 5 Gbps and clock frequencies exceeding 4 GHz. The device operates on a single supply voltage of either 2.5V ±5% or 3.3V ±10%. Key electrical parameters include a propagation delay of less than 240 ps from input to output, with rise/fall times under 110 ps. It features an internal 3-pin input termination architecture compatible with CML, PECL, and LVDS signals. The component is housed in a 16-lead QFN package measuring 3 mm x 3 mm and functions within an industrial temperature range of –40°C to +85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The -TR suffix indicates availability in tape and reel format, while other suffixes may denote tube packaging. Confirm the exact part number against official Microchip documentation to ensure correct package type and quantity specifications before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring high-speed signal routing with minimal jitter. Ensure the system power supply aligns with the specified 2.5V or 3.3V operating ranges. Verify that the input signal levels and coupling methods (AC or DC) are compatible with the internal termination requirements. Consider alternative models like the SY58017U if CML outputs are required instead of LVPECL.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to Microchip’s Precision Edge® product line, which focuses on high-speed, low-jitter solutions. It serves as a specialized multiplexer within the broader category of logic ICs designed for communication and networking infrastructure. The component integrates advanced differential signaling capabilities into a compact surface-mount package.

Signal Switches, Multiplexers, Decoders Replacement Considerations

For applications requiring CML outputs, consider the SY58017U. For designs needing 400 mV LVPECL outputs, the SY58019U is the designated alternative. These parts share similar form factors but differ in output characteristics.
